Abstract

Self-connecting telescopic antenna, of the type constituted by a plurality of tubular sections of decreasing diameters, coaxially coupled and electrically connected, characterized essentially by the provision, at the lower end of the second tubular section, in decreasing order of diameters, of a prolonged button in a frusto-conical zone followed by a cylindrical neck of smaller diameter, in turn prolonged in a guiding and stabilizing section, while the upper end of the first tubular section has a perpendicular tubular protrusion externally, which houses a lug displaceable alternately in a perpendicular direction to the axis of the antenna and displaceable by the frusto-conical zone and the body of the second section in its coaxial displacement, the said lug being integral with the end of a metal contact sheet of elongated configuration, supported on a tubular piece arranged around the first section, forming a terminal of connection and, simultaneously, the mobile contact of a switching device, whose second fixed contact is constituted by another metal sheet piece arranged parallel and isolated with respect to the previous one, with one of its ends bent and in contact with it, separating said contact at the the transverse thrust of the lug is produced by the displacement of the frustoconical section of the internal part and the temporary deformation of the first contactor element.
